This invention relates to improvements in window sash adjustors andlocks.

An object of the invention is to provide an improved window sashadjustor and lock construction which will be adjustably supported upon asash frame to automatically hold the sash in the desired adjusted openedposition.

Another object of the invention is to provide an improved window" sashadjusting and looking device which will be adjustably supported upon awindow sash for holding the window in any desired adjusted openposition, and for an tomatically locking the window sash when it isdisposed in its closed position.

A further object of the invention is to provide an improved window sashadjusting and locking device which will be entirely automatic inoperation, the same being highly efiicient and relatively inexpensive tomanufacture and produce.

Other objects will appear as the description proceeds.

Like characters of reference are used throughout the followingspecification and the accompanying drawings to designate correspondingparts.

In carrying out the invention, there is provided an improved form ofwindow sash adjusting and locking device. For purposes of illustration,there is shown a window frame generally designated by the referencenumeral I, and an upper sash frame 2 and lower sash frame 3 verticallyslidable therein, being suitably glazed at i and 5 respectively.

A locking notch or seat 6 is cut into the side wall of the window frameI in its inner surface adjacent its lower end, as clearly illustrated inFigures 1, 2 and 3 of the drawings. The upper portion I of said notch orseat 6 forms an angled locking shoulder against which the upper end of alocking member hereinafter described will engage, while the outwardlyand downwardly extending side 3 of the notch or seat 6 will be engagedby the upper side of said locking member when the lower window sash orframe 3 is in fully closed position.

The improved adjusting and locking member comprises a substantiallyrectangular shaped flat plate 9 which will be formed with an upstandingtop flange Ill, an upstanding bottom flange I I, and a connectingupstanding side flange I2. Vertically extending contact cams or bearinglips l3 and I4 are integrally formed at the juncture points of the topand bottom flanges I8 and II with the opposite ends of the side flangeI2, serving to engage the inside edge or surface of the window frame Iwhen the locking member and lower window sash frame 3 is in raised oropen position.

The body of the adjusting and locking member 20 is provided with thespaced parallel inwardly and downwardly extending slots or guideways I 5and I 6, said slot or guideway I5 being also formed with a, spur orextension slot I'I adjacent its upper end extending inwardly through themember 9, and is formed with an annular or arcuate seat portion l8 atits innermost end.

Positioning screws or lugs I9 and 2| will be placed through said slotsor apertures when the lower window sash frame is in closed position withthe adjusting and locking member or plate 9 seated in the locking notchor seat 6, to be re ceived respectively in the annular seat portion I8of the spur slot I! and in the upper end of the slot l5, as clearlyillustrated in Figure 3 of the drawings.

The screws I9 and 2| will be screwed into the lower sash frame 3 farenough to firmly support the adjusting and locking plate or member 9,but will allow for sufiicient play or movement of said member 9, as thesame moves up and down with the lower sash frame 3 to frictionallyengage the inner surface of the window frame I, thereby frictionallyclamping against the window frame with the contact or bearing lips i3and M to effectively and efficiently hold the lower window sash frameinthe desired. adjusted open position.

The mode of operation of the improved sash adjustor and lock will bemore fully explained as follows: When the lower window sash 3 is in itsfully closed position, the locking member or plate 9 will be movedlaterally until it is received in the locking notch or seat 6 formedinthe adjacent side wall of the window frame I, as clearly illustratedin Figure 3 of the drawings, thereby positively preventing anyone on theoutside of, the window sash from releasing the locking member so thatthewindow sash. may be. raised.

When it is desired to raise the window, the looking plateor member 9will be movedv laterally toward. the right-as seen in. Figure 3' of the.drawings, causing the plate to assume avertical position, asshown inFigure 4 of. the drawings. The window may thenbe raised to. the.desired. height, and due to. the inclination. of the parallel extend.-ingw slots !5' and I6 cooperating with-the securing screws l9 and 2|,movement. of the window in a downward direction will cause a lateral.movemerit of the locking plate or member Stoward the leftwor toward theadjacent. inside surface of the window frame I, thus causing the.shoulders. l3 and M at. the ends. of said plate or member 9 tofrictionally engage the adjacent inner surface of said window frame tofrictionally hold the sash in the desired. adjusted open position.Obviously, the amount of friction between the locking plate ormember 8and the adjacent inner surface of the window frame may be readilyovercome when it is desired to. lower the window or sash frame, bymerely pulling down on the. sash.

' From the foregoing description,v it will be apparent. that. there hasbeen devised andprovided a highly eflicient formof sash adjustor andlock for window constructions.

While the preferred embodiment. of the instant invention has beenillustrated and described, it will be understood that it is not intendedto limit the scope of the invention thereto, as many minor changes indetail of construction may be resorted to without departure from thespirit of the invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the UnitedStatesis 1. Means for, retaininghasashframe inadjusted open positions in a window frame; comprising a pairof upper and lower vertically spaced and aligned outwardly extendinglugs on the sash frame-adjacent the Window frame, a locking plateadjustably disposed on the sash frame and having a pair of upper andlower parallel angularly disposedguidewaysslidably supported on thelugs, outwardly extending flanges on the top and bottom of'the plate, alocking flange on one side of the plate connected with said firstmentioned flanges; a pair of cams extending outwardly in divergingdirections at theconnectingpoints between the flanges and adapted tofrictionally bear against the window frame to prevent down- Ward'travelof" the sash frame;

2. The combination of claim 1-, wherein said window frame is providedwith an inwardlyextending angular downwardly facing seat and means isprovided" for' positioning said locking plate in the seat preventingupward movement of the sash frame, said means including a lateralextension, slot disposed} on the upper guid'eway in the oppositedirectionfrom the locking flange, said extension slot terminating inanarcuate seat to lockingly engage theupper lug.
